MOWlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 386,627, dated July 21-, 1888.

Application filed September 24, 1887. Serial No. 250,551. (No model.)

To all whom it may concern.-

Be it known that I, GEORGE G. CROWLEY, of Little Falls, in the county ofHerkimer and State of New York, have invented new and usefulImprovements in Mowing-Machines, of

which the following is a specification.

This invention relates to that class of mowing-machines in which thereciprocating knifebar is actuated by a pitinan from a shaft which isdriven by gear wheels from the axle on which the groundwheels aremounted.

My invention has for its object toimprove the construction of the partswhereby the gear mechanism is thrown in and out of gear, and

1 also the parts whereby the knife-bar is actuated, supported, andadjusted.

My invention consists of the improvements which will be hereinafterfully set forth, and pointed out in the claims.

In the accompanying drawings, consisting of twosheets, Figure lisatopplan view ofa mowing-machine provided with my improvements. Fig. 2 is aside elevation of the arm and connecting parts by which the gearing isthrown in and out of gear. Fig. 3 is a longitudinal vertical section inline a m, Fig. 1. Fig. 4 is a longitudinal horizontal section in line mm, Fig. 3. Fig. 5 is a horizontal section of the mechanism by which thegearing is thrown in and out of gear. Fig. 6 is a cross-section in linex 00, Fig. 5, on an enlarged scale. Fig. 7 is-a vertical longitudinalsection of the connecting-bar. Fig. 8 is a cross-section in line :0 m,Fig. 7. Fi 9 is a horizontal section of 5 the parts connecting thepitman with the knifebar. Fig. 10 is avertical section of the same. Fig.11 is a rear elevation of the lever whereby the fingerbar is rolled.

Likeletters of reference refer to like parts in the several figures.

A represents the main frame of the machine, and A A the driving orground wheels mounted upon the axle a, which is journaled in the frameA.

5 B represents a spurgear secured to the axle a, and meshing with apinion, I), which is mounted loosely upon a horizontal arbor, 0,arranged on the frame A in front of the spurgear B.

O is a bevel-wheel formed in one piece with the pinion b, or securedthereto so as to turn therewith on the arbor c. The latter is arrangedin bearings c 0', formed in the frame A,near the ends of the arbor c, inwhich bear ings the arbor can turn and move lengthwise.

0" represents a collar secured to the arbor c and bearing against thehub of the wheel 0.

(1 represents a sleeve secured to the arbor c and bearing against thepinion b, and inclosing the end of the arborjournaled in the hearing 0.The pinion Z) and bevel-wheel C are held in position on the arbor c bythe collar 0 and sleeve cl, as represented in Fig. 5, so that the pinionI) and bevel-wheel O are compelled to follow the lengthwise movement ofthe arher 0, while being free to rotate on the same.

D represents a hand-lever secured to the outer end of the sleeve d, asclearly represented in Figs. 1, 2, and 5. The sleeve d is provided witha spiral or cam-shaped groove, (2, in which engages a fixed tooth, 0,attached to the frame, as represented in Fig. (5, so that by turning thelever D in one or the other direction the arbor c is moved lengthwise inits bearings inwardly or outwardly. The tooth e is provided with ahorizontal screw-stem, E, which passes with its outer portion through anear, 6, formed on the frame A, and projects with its inner end into asocket, 0 formed in the frame A.

c" 0' represent screw-nuts applied to the screw shank E, and bearing,respectively, against the ear 0 and socket 0", thereby enabling thetooth c to be adj usted' horizontally in a direction parallel with thearbor c.

0 represent lugs formed on the outer side ofthe ear e, and bearingagainst the upper and lower sides of the tooth 0, whereby the latter isprevented from turnin f represents the longitudinal shaft, which isarranged in front of the arbor c, and provided at its front end with thecrank-wheel F and at its rear end with a bevcl-pinion,f, with which thebevel-wheel O can be made to mesh. In Fig. 1 the bevel-wheel O is shownout of gear with the pinionf. Upon turning the hand-lever D backwardlythe cam-groove d and tooth 6 cause the arbor c to move toward the pinionf, whereby the wheel 0 is thrown into gear with the pinion f, asrepresented in Fig. 5. By adjusting the tooth e the proper mesh isreadily obtained, so that the wheel 0 meshes neither too hard nor tooloosely with the pinionf. The teeth of the pinion I) are made longenough to remain in mesh with the spurgear B in the various positionswhich the pinion assumes as the arbor 0 is moved to throw the wheel 0 inand out of gear.

G represents the transverse connecting-bar, connected at its inner endto the front extension of the frame A, near the crank-wheel F, andhinged at its outer end to the shoe H by two longitudinal pivots, h it.The front extension of the frame A is provided with two ears, 9 9,between which is pivoted an eyebolt, I, by a longitudinal pivot, j. Thesciewthreaded shank 'i of the eyebolt enters a screwthreaded socket. i,formed at the inner end of the connectingbar G. The shank i turnsloosely in the socket i, so that the connectingbar is by this meansswiveled on the eyebolt. This permits the free movement of theconnecting-bar when the cutter-bar is rolled back and prevents crampingand binding of the parts, while it forms a very simple means ofconnection between the bar G and theframe.

K represents the pitmamwhich is provided at its outer end with ahorizontal pivot, 70, preferably formed in one piece with the pitman.This pivot passes through an eye, Z, in the head L of the knifebar Z,and is provided near its end and at the rear side of the knifehead witha notch, which extends partly around the pivot, as represented in Figs.9 and 10.

M represents a spring-bolt, which engages with its head on in the notchin, and which is attached to the rear side of the head L. The shank ofthe bolt M passes through a easing, m, formed on. the rear side of thehead L, and containing a spring, m, whereby the head of the bolt is heldin engagement with the pivot 76. Upon forcing the spring-boltM back, sothat it becomes disengaged from the pivot, the latter can be withdrawnfrom the eye 1, thereby disconnecting the pitman from the knifebar. Uponinserting the pivot into the eye Z the pivot is automatically locked inposition by the spring-bolt. The notch 7c is made long enough to permitof the requisite rocking motion of the pivot.

The bolt M is prevented from becoming disengaged from the casing m by apin in the end of the bolt.

N represents the pole secured to the outer side of a longitudinal arm,a, formed on the main frame A in front of the axle a.

0 represents an auxiliary frame secured to the outer side of the pole Nby transverse bolts o, which pass through the auxiliary frame 0, pole N,and arm a, and these parts are held in their proper relative positionvertically by' formed of cast-iron and strengthened by a brace, 0*, ofwrought-iron, which connects the front and rear ends of the frame andpassrs through a central lug, 0, on the frame. The wrought-iron brace 0is secured in the auxiliary frame by being cast into the same. The rearend of the brace 0 projects laterally beyond the frame 0 and forms apivot, 0

P represents the thrust-bar, which is supported with its rear end on thepivot 0 and connected with its front end to the transverseconnecting-bar G, near the shoe H, bya hori- Zontal pivot-bolt, p,passing through upright lugs or arms 1), formed on the bar G and holdingthe thrust-bar between them, as clearly represented in Figs. 3 and 11.

p is the hand-lever, by which the finger-bar is inclined or tilted, andwhich is mounted on the pivot 0 between the thrust-bar P and theauxiliary frame 0. The latter is provided at its rear end with a notchedsegment, 1), in which engages a catch attached to the lever 19 wherebysaid lever is locked in position.

q represents a rod connected with its rear end to the hand-lever p, andwith its front end to a lever, Q. by which the finger-bar is' rolled,tilted, or inclined. The tilting-lever Q is constructed in the formof averticallyelongated loop, as represented in Fig. 11, and it is pivotedupon the same-bolt, p, by which the thrust-bar P is connected with thetransverse bar G. This bolt 12 is arranged in line with the eyebolt I atthe inner end of the bar G, as represented in Fig. 7, in order toprevent binding of the parts when the transverse bar G is turned on theeyebolt. The lever Q straddles the lugs 19 of the bar G, and its lowerarm bears against the rear side of the bar G, while its upper armprojects above the same, and is connected with the front end of the rodq, as represented in Fig. 3. By adjusting the handlever 19 the lever Qis turned on the pivot 10, whereby the transverse bar G is turned on theeyebolt I, and the finger-bar is rolled in one or the other directionand its inclination regulated. The front end of the rod g is providedwith a vertical hook, q, which engages in a horizontal eye, 1 in thelever Q. This construction permits the rod to be readily attached to thelever before these parts are attached to the reach, and prevents theparts from becoming separated when in the normal position.

R represents the bearinglever, which is arranged lengthwise on thetransverse connecting-bar G and pivoted on the pivot r to the under sideof the latter, as represented in Fig. 7. The short lower arm of thelever B bears upon the shoe H on the inner side of the pivots of thelatter, and the long upper arm of the lever B extends inwardly over thebar G through openings win the lugs 12 thereof. The inner end of thelong upper arm of the lever B is connected by a chain, r, with the shortarm 8 of a hand-lever, S, by which the fingerbar is raised and lowered.The lever S is mounted upon a pivot, s, secured to the front end of theauxiliary frame 0, which latter is provided with a notched segment, 3upon which the lever S islocked byasuitablecateh, 8. Upon raising theinner end of the bearinglever B by the hand-lever S the inner end of theshoe is first depressed and the outer end of the finger-bar raised untilthe lever B reaches the upper ends of the openings r,when the turningmovement of the lever R on its pivot ceases, and the finger and thetransverse bar G are raised together.
